Abstract

The bending tool for tubes (8) and similar includes a mandrel shaft (15) movable into and out of the tube cavity. During bending, it is on a bend line between at least two opposed rollers (11-14) applying bending pressure. The mandrel shaft is highly resistant to pressure and wear, at least in the region of the bend line.
